How do US tax brackets work?

The US uses a progressive marginal tax system. Each dollar of income is taxed at the rate for the bracket it falls into, not at your "highest" rate across all income. For example, if you're in the 22% bracket, only the dollars above the 12% bracket threshold are taxed at 22%. The portion below that threshold is still taxed at 10% and 12% respectively. Your "effective tax rate" — total tax paid divided by total income — is always lower than your marginal (highest) bracket rate.

What is the difference between deductions and credits?

Deductions reduce your taxable income, which indirectly reduces your tax bill based on your marginal rate. A $1,000 deduction saves you $220 in taxes if you're in the 22% bracket. Credits, on the other hand, directly reduce your tax bill dollar-for-dollar. A $1,000 tax credit saves you exactly $1,000, regardless of your bracket. This makes credits generally more valuable than deductions of the same dollar amount.

What is the standard deduction?

The standard deduction is a flat amount you can subtract from your gross income without needing to itemize individual deductions. For 2025, the standard deduction is $15,000 for single filers and $30,000 for married filing jointly. Most taxpayers benefit from taking the standard deduction rather than itemizing. You should only itemize if your total qualifying deductions (mortgage interest, charitable donations, state taxes, medical expenses) exceed the standard deduction amount.

Should I contribute to a traditional or Roth retirement account?

This depends on whether you expect your tax rate to be higher now or in retirement. Traditional (pre-tax) contributions reduce your taxable income today and are taxed when withdrawn in retirement. Roth (after-tax) contributions provide no current deduction but are withdrawn tax-free in retirement. If you're in a low bracket now and expect higher income in retirement, Roth is generally better. If you're currently in a high bracket and expect lower income in retirement, traditional is usually more advantageous.
